UNITED STATES PATENT QFFICEO THOMAS MILLER, OF JERSEY OI' IY, NEW JERSEY.

LAMP-EXTINGUISHER FOR RAILROAD-CARS.

SPECIFICATION forming part'of Letters Patent No. 379,121, dated March 6, 1888.

Application filed February 21, 1887.

To all whom it may concern:

Be it known that I, THOMAS MILLER,Of J ersey City, Hudson county, New Jersey, have invented a new and useful Improvement in Lamp Extinguishers for Railroad Cars, of which the following is a specification.

My invention consists ofimproved contrivances whereby the lamps of railroad-cars may be extinguished by air -jets automatically turned on from the compressed-air holder of the brake apparatus or other holder when the car is violently thrown over or severelyjarred, as in collisions andother accidents, to prevent the disastrous conflagrations now so common in such cases, as hereinafter fully described, and pointed out in the claim, reference being made to the accompanying drawings, in which Figure l is a transverse section of a car, showing an arrangement of apparatus in which my invention can be carried out by the use of a vibrating pendulum-lever for opening the valve to let on the air-jets. Fig. 2 is an outline of a car in longitudinal section, further illustrating the application of the invention; and Figs. 3 an l4 are respectively longitudinal and cross-sectional detail views of the valve.

From any suitable compressed air holder as the holder a of the compressed-air-brake system; but it may be'any other, as one specially provided for the purpose and having suitable means of charging it with air under compression-J arrange main pipes 12 c and branches d for delivering a jet to each lamp e to extinguish all the lamps, when required; and for eflecting the opening of the pipe automatically, by means that may be set in action by such. violent shocks as the cars are subject Serial No. 228,278. (No model.)

to in collisions and the like accidents, I employ any suitable valve or cock, f, with a weighted arm, g, that will turn or slide the valve according as the car falls down lengthwise or rolls sidewise, as in Figs. 1 and 2.

In this example I have represented the cock f as capable of opening the passage to let on the air either by turning on its axis or sliding lengthwise either way, and have connected the pendulum-lever g to the stem and suspended said pendulum-lever by a chain, h, to support it mainly and relieve the valve of lateral stress, and so that the swinging of the pendulum-lever on the axis of the stem, either forward or backward, as the car may happen to fall or be thrown up lengthwise or comein violent collision with other cars or objects, will turn and open the way, and the thrust of the weight sidewise of the car will shift the valve lengthwise and open it that way; but the contrivan ce may be varied in this respect at will.

I prefer to arrange a second holder, a, between the holder aand thelamps, with a checkvalve, 0, between them, so that when holder n is charged from holder at there will be no escape from a when holder at is temporarily discharged in the working of the brakes.

What I claim, and desire to secure by Letters Patent, is-

The combination, with the lamps of a railroadcar, of a compressed-air holder, pipes for extinguishing the lamps extending from the holder to the lamp-burner, the oscillating and sliding cockf, and the pendulum-lever 9, substantially as described.
